    I have installed oracle 11g and tried to take full backup of that. I set parameter log_archive_dest_1 to D:\backup\. I got the backup file created in supposed folder but logs are not getting created and showed error rman – 03002. The command I typed from rman prompt is given below.

    run {
    allocate channel t1 type disk;
    allocate channel t2 type disk;
    backup as compressed backupset filesperset 4 database format ‘D:\backup\online_full_%d_%s’;
    backup as compressed backupset archivelog all;

      Welcome Gaurav,
      My first question – What logs are you referring to …? (If Archive logs, please check if you have the archive log mode enabled)
      Where and when you are getting ORA-03002 .. ?

      Data corruptions (Most of the times)

      1. Find out the DBINC_KEY on the rman database (Recovery catalog)
      SQL> SELECT NAME, RESETLOGS_TIME, DBINC_KEY FROM rc_database_incarnation WHERE dbid=xxxxxxxxxx;

      *Note: to identify DBID —
      [oracle@prashant1 ~]$ rman target /
      Recovery Manager: Release – Production on Sat Nov 23 21:22:39 2013
      Copyright (c) 1982, 2005, Oracle. All rights reserved.
      connected to target database: QRCL (DBID=859215136)

      select name, dbid from v$database;

      2. Find out the problem file#
      SQL> SELECT dbinc_key, ts#, ts_create_scn, file# FROM tf WHERE DBINC_KEY=yyyyy;

      3. Take a note and remove the record from tf.
      4. Do a resync catalog using RMAN

      Good Luck!
